  Gists referred from [[https://emacs.ch/@bram85][@bram85@emacs.ch]].

  Unfortunately gitea has no gist support and there's no mature yet lightweight gist solution suitable for self-hosting, so resorting to this poor-man's setup of sharing gists with an audience.

  - State "DONE"       from "TODO"       [2022-11-26 Sat 07:57]
  :END:

  A small org file to keep track of some metric in a table, see [[https://orgmode.org/manual/Results-of-Evaluation.html][Results of Evaluation]] in the Org mode manual for more information.

  In this case, count the number of packages in my Emacs init file. The code will automatically mark the task as DONE (thanks to [[https://emacs.ch/@leadore@toot.cafe/109406486013699362][@leadore@toot.cafe]]).

  Press =C-c C-c= inside the code block to add a new entry to the table below.

  ,#+begin_src elisp :results table append
    (save-excursion
      (org-back-to-heading t)
      (org-todo "DONE")

      (with-temp-buffer

** Idea: event handlers :idea:

Have =ON_<STATE>= properties containing code that evaluates when that state is reached. Can be looked up and evaluated from =org-after-todo-state-change-hook=.
